East Baton Rouge Parish, LA Building Safety: Building Permits (2026)

East Baton Rouge Parish's building-permit trigger is broad: Sec. 8:500 requires any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure, or to install, alter, repair, remove, convert or replace an electrical, gas, mechanical or plumbing system, to first apply to the building official and obtain a permit. Sec. 8:501 then carves out a list of specific small-scale exemptions that need no permit at all, including one-story detached accessory structures like tool sheds and playhouses under 200 square feet, on-grade water tanks holding 5,000 gallons or less, ordinary painting and finish work such as tiling and cabinetry, temporary movie and stage sets, and small prefabricated swimming pools under 24 inches deep.

Sec. 8:501 makes clear an exemption from the permit requirement does not excuse compliance with the underlying building standards or any other ordinance. Under Sec. 8:801(5), most other residential permits, including additions, renovations, generators, pools, fences, solar installs and driveways, carry a flat $125 fee, while a new residential building permit fee is folded into the plan review charge. Commercial work is billed on a sliding per-$1,000-of-valuation scale under Sec. 8:801(3). Once issued, Sec. 8:509 voids a permit if work has not started within 180 days, or is suspended for 180 days after starting, subject to written extensions from the building official. Sec. 8:511 requires the permit be posted and kept visible at the jobsite for the duration of the project.
